kWILLIAM ovEsoN, oF gesuita, MINNESOTA' Y 's'rUMr BULLER This invention relates to a device for pulling stumps, trees and the like, the general oloject of the invention being'to so. construct andarrange the parts that the lift is perpenv dicular instead of horizontalso that the pulli ing force is exerted in a ,vertical'directiom which is the logical one, as the natural growth of a trees roots is to vresist wind from the sides so that the roots oder more resistance y when a stump is pulled by means which exert ing on top of the roots.

Another object of thevinvention is to provide means whereby thecable can be wound on the drum by either hand power or motive power and also to provide braces for the upper end of the crane which maybe-adjusted to suit conditions.

This invention also consists in certa/in other f features of construction and 1n the combina-v tion and arrangement of the several parts, to

be hereinafter fully described, illustrated in j, u v Y theidrumgisgto bei-rotated hand, `the clutch g meansvshould be in inoperative positionl Y The v.cable LILOV passesvupwardly above thef' Y i the accompanyingA drawings and specifically pointed outin the appended claim, In describing theinvention in detailfreference will be had to )the accompanying VFa',sli-cave 24 carried at the front end-of the Y The V cable then passes `downwardly wardlyovera sheavev26ainethe block :26 which iS atthedft the beam, and than downward- "lyilove'nanother sheave25igin theblock'25 and Y drawings wherein likecharacters denote like or corresponding parts-.throughout the' sevf eral views, and in which :L-

Figure 1 is an elevation ofthe invention.

Figure 2. is a top plan view thereof.` Figure 3 is a frontvview.Y

In these views, the numeral f1 indicates a sled-like base on which the various :parts of the device are arranged so that the device 40 can be easily transported fromplace to place.

A crane V'for-minglbeam 2 is. diagonally supported on the base with its lower end fastened to the base yand with its upper end extending well beyond the rear of the lbase,l a pair of braces 3 being connected'with an intermediate portion of the beamand" to the base.

Truss rods 4 are y'connectedwith.the base adjacent the bottom ofthe beam andfthese truss rods pass .over a block 5 on the beam at' about the center thereof and have their Lup- @belt ,14 passes `overthis pulleyl and over :,course, be understoodjthatthe clutch jmeans Per eil-lds Connected .withff'the "bracket c .at-'' tachedfto the upper-rend ofthe beam. A'shaft 7 ljournaled,in:theuprights 8 onthefrontr Y Vof ,the base .and saidA shaft carries =theidrum y '9 forthe `cable 10. The `drum isprovidedg f f with ,theusiial ,brake means ,1l which ,are-.op- A erated by the brake lever l2V and a pulleyl is loosely arranged .onfthe druml shaftjandwa pulley ll5rwhch is suitably connected to the `shaft of :afmotor 16 .on ythe base. gFriction clutChxnean'S, .shown `general-ly at 17, are pro` fvidedvforv cqnnecting the pulley 13 witlrthe fxdrum .shaft or .disconnectingit therefrom,

the lever. suchclutch means being shown O i Asliaft 1`9is journaled in the uprights and il .has Aa fhandwheel 20.011 its outer end,` said shaft carrying pinion2l which-meshes with agear 22 (on the drum. .Thus the drum can Z0 @be eitherrrotated byhand throughmea-ns of f the handzwheel 2O lor through :the motor t f y ,through belt-and pulleys.. It will, of

'A 'pair of brace legs 28l have their'uppei` ends'pivotally'connected with the upper end of the beam, as shown at 29, so'that these legs can beladjusted to any. angle to support' any lifting strain on the crane. p

Fromthe foregoing -it will be seen that the 59,5 pullexerted by the cable on the block which Y is attached to the stump or tree is in a vertical direction which, as'before statedfis the logical one, as the roots, of a stump or .tree will oer least resistance to such a pull. Y

" tion that the advantages and novel features It is thought from the foregoing descripof the invention will be readily apparent.

It is to be understood t-hat changes may y vbe lmade inthe construction and in the combination andA arrangement of the several parts,

provided that such changes fall within the scopeof the appended claim.V

What I claim is Stump pulling' apparatus comprising a base, a beam mounted at its forward end upon the base, the beam being upwardly and rearwardly inclined and extending a considerable distance beyondthe rear end of thev Y base, braces at the rear end of the base for supporting the beam inwardly of its rear end, bracing members pivotally `connected at their upper end to the beam at opposite sides of the rear end thereof and extendingdowlr.v

wardly and rearwardly therefrom and `diverging outwardly with relation to each A other, a vpulley mounted at the'upper rear end of the beam, a block at the upper rear end of the beam, a block below the first mentioned block, ya pulley mounted in the first vmentioned block,'a shaft mounted upon the base at the forward end thereof7 a drum upon the shaft, a cable connected to the drumto be wound thereon and unwound therefrom, and means for rotating the shaft comprisinga motor mounted upon the base and between the drum andthe rear end of the base,'an idle pulley mounted upon the upper side of the beam between the ends thereof, the cable being passed beneath said idle pulley and over the pulley first mentioned, pulleys rotatably mounted in the second mentioned block, the

cable'being led downwardly from the first mentioned pulley and beneath one of the pulleys of the last mentioned block, thence upwardly and over the pulley of the first mentioned block, and thence downwardly and beneath the other pulley of the second Vmen tioned block andupwardly therefrom and anchoredjto vthe first mentioned block, the

'blocks being invertical alinement with each other between thefirst mentioned braces,and

vthe Vdownwardly andfrearwardly inclined Irelatively diverging braces,

vthe last mentioned block for lblock with means to be anchored to' the'stump rto be=pulled. I In testimony whereof I affix my signature.
